  1. 6. Concrete Bridges : Improved Load Capacity

    Författare :Jonny Nilimaa; Terje Kanstad; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Structural Engineering; Konstruktionsteknik;

    Sammanfattning : There are many beautiful old structures around the world, some of which were designed for completely different purposes than their current applications. For example, Swedish railway bridges were only designed to carry axle loads up to 200 kN in the beginning of the 20th century, while modern loads can be twice as high. LÄS MER

  3. 7. Constipation : symptoms and findings in relation to structural and functional abnormalities

    Författare :Abdulhakim Glia; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :constipation; defecation; electromyography; gastrointestinal motility; immunchistochernistry; intestinal pseudo-obstruction; physiopathology; quality of life; transit time;

    Sammanfattning : The aim of this study was to increase the knowledge about functional constipation with special reference to symptoms analysis, laboratory investigations and histopathology findings. 155 consecutive patients with intractable constipation underwent anorectal manometry, electromyography (EMG), balloon expulsion test, colonic transit time, and defecography.

  4. 8. Blood pressure, renal functional and structural changes, in normal and preeclamptic pregnancy

    Författare :Helena Strevens; Lund Obstetrik och gynekologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Obstetrics; renal biopsy; renal function; pregnancy; preeclampsia; physiology; parity; endotheliosis; cystatin C; Blood pressure; BMI; gynaecology; andrology; reproduction; sexuality; Obstetrik; gynekologi; andrologi; reproduktion; sexualitet;

    Sammanfattning : The kidneys play a pivotal role in the adaptive physiology of the pregnant woman, presenting some changes at term similar to the changes found in preeclampsia – a state of increased risk of fetal and maternal morbidity and mortality. The aim of these investigations was to explore possible similarities in blood pressure regulation, renal function and structure in normal term and preeclamptic pregnancy, to ascertain whether both conditions in fact are different degrees of an adaptive process in reaction to pregnancy.

  5. 9. 3D structural framework and constraints on the timing of hydrothermal alteration and ore formation at the Falun Zn-Pb-Cu-(Au-Ag) sulphide deposit, Bergslagen, Sweden

    Författare :Tobias Christoph Kampmann; Pietari Skyttä; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Malmgeologi; Ore Geology;

    Sammanfattning : The Falun pyritic Zn-Pb-Cu-(Au-Ag) sulphide deposit, situated in the Palaeoproterozoic (1.9–1.8 Ga) Bergslagen lithotectonic unit in the south-western part of the Fennoscandian Shield, is one of the major base and minor precious metal sulphide deposits in Sweden. LÄS MER

  7. 10. Structural evolution of two ore-bearing Palaeoproterozoic metasupracrustal belts in the Kiruna area, Northwestern Fennoscandian Shield

    Författare :Joel Andersson; Tobias Bauer; Olof Martinsson; Luth Stefan; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : In this project, two key study areas in the northwestern Fennoscandian Shield are under investigation. The “Western supracrustal belt” and “Central Kiruna area” are both located along lithotectonically comparable Rhyacian-Orosirian metasupracrustal belts and both areas are characterized by iron oxide-apatite (IOA) and iron oxide-copper-gold (IOCG)-style mineralizations and related hydrothermal alterations.
